Is there any hope for osteosarcoma bone metastasis? If osteosarcoma develops bone metastasis, there is still hope for treatment. However, once metastasis occurs, the treatment costs, difficulty, and prognosis tend to be relatively unfavorable. Additionally, osteosarcoma itself invades and damages the bone. As the disease progresses, it stimulates osteogenesis which eventually leads to both bone formation and damage. Generally, the appearance of osteogenic changes often indicates a shift towards a better prognosis for the bone. Therefore, if osteosarcoma has metastasized, while treating the primary lesion of the tumor, it is also crucial to actively treat the metastatic sites. Thus, the difficulty of the treatment and the prognosis might not be very optimistic, but it certainly hasn't reached a point where the disease is untreatable. Therefore, once osteosarcoma metastasizes, it is recommended to visit the oncology department of a reputable hospital for systematic treatment by a doctor.

Is there a cure for osteosarcoma?

Osteosarcoma is treatable, but it requires proper medical treatment. Currently, adjuvant chemotherapy significantly improves the five-year survival rate for osteosarcoma. The main treatment approach is still surgery as part of a comprehensive therapy. Specifically, the first step involves adequate preoperative chemotherapy, generally no fewer than six sessions over about eight weeks, or approximately two months. After this, patients often experience reduced pain, weight gain, improved positioning of the tumor, and a decrease in tumor size. Depending on the specific situation, a decision is made on the type of surgery to be performed—whether to amputate, preserve the limb, install a prosthetic, or use artificial bone as a replacement. Postoperative chemotherapy is usually also required to help ensure that the tumor does not recur and to increase the five-year or ten-year survival rate. Therefore, the current five-year survival rate for osteosarcoma has increased from the previous 40%-50% to about 80%. So, as long as one chooses the right hospital and the right treatment plan, and maintains confidence, osteosarcoma is usually treatable.

Osteosarcoma imaging manifestations

The radiological features of osteosarcoma start with an introduction to X-ray imaging. X-rays can show typical new bone formation and bone destruction, which are characteristic features of X-rays. Destruction of bone trabeculae can also be seen on X-rays. Additionally, the density of the tumor tissue increases, leading to a characteristic X-ray known as the Codman's triangle, which occurs when the tumor penetrates the bone and pushes up the periosteum, creating a unique image of Codman's triangle. The second examination includes CT scans and MRI, which are primarily used to determine the nature and extent of the bone tumor, and whether there is infiltration into the surrounding soft tissues. The third radiological examination is a nuclear bone scan, which is primarily important for determining whether the myeloma has metastasized to distant sites.

What is the metastatic pathway of osteosarcoma?

Osteosarcoma commonly spreads in three ways. The first is through hematogenous dissemination, meaning that tumor cells spread throughout the body via the bloodstream, a process known as hematogenous spread. The second method is called implantation metastasis, where tumor cells directly implant in the common sites of osteosarcoma, leading to localized disease. The third type is lymphatic spread, where tumor cells spread to multiple parts of the body through the lymphatic system, causing new tumor growth. These three pathways are the most common routes of metastasis seen clinically in osteosarcoma, with hematogenous spread being the most frequent.

Osteosarcoma is malignant.

Regarding whether osteosarcoma is benign or malignant, it is certain that osteosarcoma is a malignant tumor with a very high degree of malignancy. Once osteosarcoma is definitively diagnosed, aggressive treatment is necessary. Surgery is the main treatment approach, aiming to perform as extensive a resection as possible, or amputation may be required when necessary. After surgery, the resected specimen must be sent for pathological examination. Based on the type of pathology, the next step in treatment, either radiotherapy or chemotherapy, will be determined to minimize the recurrence of osteosarcoma, as a recurrence can endanger the patient's life.

How to alleviate the pain of osteosarcoma?

Pain in osteosarcoma patients is mostly caused by the cancer invading local bone tissue and other tissues, leading to pain, tenderness, and even sleeplessness. Therefore, the pain management follows a certain hierarchy, starting with non-steroidal anti-inflammatory drugs, followed by weak opioids, and finally strong opioids such as morphine. However, this only alleviates the pain and does not help with treatment. For early-stage osteosarcoma patients, pain management primarily involves surgery when necessary. For advanced-stage patients, it involves gradually increasing the dose of effective pain-relief medications to alleviate temporary pain. (Controlled drugs must be strictly used under the supervision of relevant physicians.)
